The results were analyzed by using Fuoss-Onsager conductance equation and Walden's equation, and discussed from the point of view of solvent structure.In the vicinity of azeotropic mixture, conductance behavior of (Et_4N)^+, which is considered to have hydrophobic interaction with solvent is quite different from those of Cl^-, Br^-, I^- which are considered to have ionic interaction with solvent. The Stokes' radious of (Et_4N)^+ becomes maximum in the azeotropic mixture, while those of Cl^-, Br^- show minima, but Stokes' radious of I^- appears to be rather small maximum in the mixture.From the data about the ionic conductance and Stokes' radious of (Et_4N)^+, it is considered that the hydrophobic interaction increases in the vicinity of Water-n-PrOH mixture (n-PrOH:10.72mol%).In the Water-n-PrOH mixture, the partial molar volume and mixing heat become minimum values at the region of 5 to 7 mol% of n-PrOH concentration. Therefore at this region, the alcohol molecule will go into the cavity of water structure. When the alcohol concentration increases above this region, the water structure will be broken down and produce new hydrogen bond of water-alcohol, at the same time, water molecules which have less hydrogen bond will be produced those water molecules will make hydrophobic interaction with (Et_4N)^+. In the vicinity of azeotropic mixture, those water molecules will be maximum in number. Above this region, therefore, as　increasing n-PrOH concenration, the number of those molecules will decrease and hydrogen bond between water and n-PrOH will be increasing in the region investidgated here.","subitem_description_type":"Other"},{"subitem_description":"紀要論文","subitem_description_type":"Other"}]},"item_1617186643794":{"attribute_name":"Publisher","attribute_value_mlt":[{"subitem_1522300295150":"ja","subitem_1522300316516":"琉球大学理学部"}]},"item_1617186702042":{"attribute_name":"Language","attribute_value_mlt":[{"subitem_1551255818386":"jpn"}]},"item_1617186783814":{"attribute_name":"Identifier","attribute_value_mlt":[{"subitem_identifier_type":"HDL","subitem_identifier_uri":"http://hdl.handle.net/20.500.12000/8331"}]},"item_1617186920753":{"attribute_name":"Source Identifier","attribute_value_mlt":[{"subitem_1522646500366":"ISSN","subitem_1522646572813":"0286-9640"},{"subitem_1522646500366":"NCID","subitem_1522646572813":"AN00250774"}]},"item_1617186941041":{"attribute_name":"Source Title","attribute_value_mlt":[{"subitem_1522650068558":"ja","subitem_1522650091861":"琉球大学理学部紀要"},{"subitem_1522650068558":"en","subitem_1522650091861":"Bulletin of the College of Science.
